Most people have either become infected or have been killed by the parasitic Devil Worm and have become "Zombie-like" beings called the Ridden. It's up to you to help rid the world of these monstrosities as apart of a squad called the Cleaners. You will no longer be looking for shelter to hide in, but instead clearing hordes of zombies to make areas safe once again.

There is also an eight-player PvP mode, where players can take on the form of a mutated zombie to give the Cleaners a rough time. Along with these modes is the addition of something called the Game Director. The game director will show a set of corrupted cards that provide a wide variety of randomized variables for each mission.
